I tried to install puppet enterprise from puppet master and while selecting monolithic installation and setting upto 500 nodes and setting up the DNS name and the alias name and encountered an error
WARNING 1: set 2 CPU cores instead of 4 CPU cores
WARNING 2: set at-least 100GB space in /Opt folder.
And i ended up in the following error
"Error: Could not start Service[pe-puppetserver]: Execution of '/bin/systemctl start pe-puppetserver' returned 1: Job for pe-puppetserver.service failed.
